Webhooks

Hydra can be notified by github's webhook to trigger a new evaluation when a jobset has a github repo in its input. To set up a github webhook go to https://github.com/<yourhandle>/<yourrepo>/settings and in the Webhooks tab click on Add webhook.

• In Payload URL fill in https://<your-hydra-domain>/api/push-github.
• In Content type switch to application/json.
• The Secret field can stay empty.
• For Which events would you like to trigger this webhook? keep the default option for events on Just the push event..

Then add the hook with Add webhook.
